[Freeswitch-users] Problems with Mod_openMRCP

Mon Dec 1 23:00:32 PST 2008

 I need to barge in again and add to my last post with this email from Voxeo support. Here is their response to the port binding conflict and it brings up a possible problem if FreeSwitch will be looking for Prophecy at that port? I assumed it would if I set up the extension right but now I don't know and need your assistance with this issue ... as well. 

Thank you.

MESSAGE:
Hi Mark,

You are correct in that having multiple applications binding to the same port 
can cause a bundle of problems. You can configure Prophecy to stay away from 
port 5060, but then the question is whether FreeSwitch will be looking for 
Prophecy at that port (if its assuming that it's residing on a different box). 
Port 5060 is the standard for SIP traffic.

To get Prophecy off 5060 you will need to edit the config.xml and 
callrouting.xml files. You will need to search out all instances of "5060" and 
replace with, perhaps, port 5068. For instance:

<item name="ListenOnIP1">0.0.0.0:5068</item>
<item name="ListenOnIP2">0.0.0.0:5061</item>
<item name="ListenOnIP3">0.0.0.0:5067</item>
<item name="ListenOnIP4">0.0.0.0:5063</item>
<item name="ListenOnIP5">0.0.0.0:5064</item>
<item name="ListenOnIP6">0.0.0.0:5065</item>

instead of this...

<item name="ListenOnIP1">0.0.0.0:5060</item>
<item name="ListenOnIP2">0.0.0.0:5061</item>
<item name="ListenOnIP3">0.0.0.0:5062</item>
<item name="ListenOnIP4">0.0.0.0:5063</item>
<item name="ListenOnIP5">0.0.0.0:5064</item>
<item name="ListenOnIP6">0.0.0.0:5065</item>

 Just to follow up.

Moshe Yudkowsky has an article on "Routing calls from FreeSwitch to Prophecy":? http://www.prophecy2006.com/node/145

My problem is that Freeswitch and Prophecy need to be on the same machine BUT both need to bind to port 5060 so I'm getting errors from one or the other depending who's running first.

So can I change what port(s) FS uses and that way avoid this conflict? 

Maybe, this might let me bridge the call via FreeSwitch to Prophecy similar to what Moshe's article discusses???

 Does "bridging" a call from FS to Voxeo's Prophecy server require openMRCP? If not then the other issue I might have is a database look up that is part of the dialogue that maybe need as the person response to prompts from the asr. It's possible to run a php script for the database stuff that Prophecy might need or could that happen via Javascript in FS? Then after the dialogue has completed I go from Prophecy back to FS.

mod_openmrcp was a contribution to the community by a 3rd party individual.

As i have clearly stated in 2 previous emails, the man has decided to discontinue the openmrcp project.

So now we are left with the remains of the module and discontinued code.? This was not our decision it was his. 

Since the author of openmrcp has stated that he has a new unimrcp we are certainly going to 

work towards getting mod_unimrcp to replace mod_openmrcp.? He had already commented on that previous thread to state he is willing to consider making a new module.

Some people use it without issue which may mean that the crash you reported is windows specific and I do not have a working lab of any mrcp capbable system to try it against in unix for that matter.? I have a list of work to do from here to the moon and back so on an issue like this, unless someone can hand me login credentials to some box and give me a phone number to dial to reporduce the issue, it will be a long time until we can deal with it.? And the question arises, should we bother working on it anymore if the lib has been abandoned and we cannot even get any support from it's author which is where the problem most likely lies.

I try not to get too annoyed by these remarks about what we *ought to do* because I know people lose sight of how much of the work to support the project is done by a small group of 3 people and not the 2000 people it appears to be from the outside looking in. (I've been answering email for 4 hours now) 

My suggestion is to pool some cash and pay the guy to make mod_unimrcp for FS that we can maintain in tree knowing the development can be supported by the original author.

Hi Mike,

My experience is that it's somewhat broken - it took two trivial tweaks
to get it to work with IBM's ASR and TTS, but there's a more
intractable problem to do with memory getting overwritten (I assume
that this is something to do with something being freed when it
shouldn't be) which causes a segfault on the second or third session
after the module being loaded.

Without wishing to sound like a stuck record, one thing that you guys
really ought to do is to decide what's supported and what isn't, and
make this obvious - for example, move unsupported modules to a
different place in the tree, don't have them built by default, etc.?
MRCP is in the specsheet on the Wiki.? Otherwise folk like Mark and I
spend time installing stuff, go round in circles a bit trying to make
it work, and then find out (a) that it doesn't and (b) it's not going
to be fixed because it's not supported.

I would not say it is totally broken, it is known to work
in quite a few places, but we are unlikely to be doing any new fixes in
it.

 Hi Anthony,

Oh! OK.

So is this module "totally broken". 

I say this because I can't seem to get it to work at all with the
example in that Mod_openmrcp wiki page but I thought it might because
I'm not be using the right Cepstral software (freetrial download versus
the paided for SDK) or that I'm not using the right port numbers or
something else I didn't do. I used TcpView to look at local port
associated with my Cepstral software and changed a few things but still
nothing. I changed the loglevel setting to 7 in the wiki's example but
I don't see the kind of output on the console that I would expect for
debug mode.

Thanks. Mark.
